ABSTRACT:
FIELD OF THE INVENTION
The present invention is generally related to waste receptacles and is more particularly related to a waste receptacle having a bag storage compartment therein and separable receptacle walls that facilitate access to the bags stored in the storage compartment.
BACKGROUND OF THE INVENTION
A wide variety of waste receptacles are commercially available. Waste receptacles can range in size from about one liter up to the approximately 215 liters (approximately 56-gallons). Plastic bags are often used to line the waste receiving space in a waste receptacle, particularly if the waste disposed in the receptacle is moist, such as kitchen waste, or is contaminated or hazardous, such as hospital waste. Most plastic liner bags are made of polyethylene or polyethylene. Plastic bags are often provided to the end user as a continuous roll of bags. Each bag in a particular roll has a leading open end and a sealed end that is removably secured to the open end of the next succeeding bag in the roll.
Because bags are usually not reused, they are replaced each time the receptacle is emptied. It is desirable to store a supply of new bags at the location of the waste receptacle so that a new bag is readily available when the receptacle is emptied. It is also desirable to be able to quickly and easily remove a new bag from the supply of bags in the storage area and place it in the waste during the bag replacement procedure.
Bag dispensers that are located in waste receptacles are known. For instance, U.S. Pat. No. 5,881,900, describes a waste receptacle that contains a space for storing and dispensing new bags for lining the receptacle in the base of the receptacle. While such a receptacle alleviates the problem of finding a new liner bag, it does not satisfactorily provide ease of access to a new liner bag nor does it adequately address the difficulty of removing a full bag of waste from the receptacle.
There is a need for a waste receptacle having a receptacle portion that can be easily opened to facilitate removal of a full bag of waste and having a bag storage space constructed and arranged to supply a new bag in the receptacle when a full bag is removed.
SUMMARY OF THE INVENTION
It is an objective of the present invention to improve upon the aforementioned waste receptacles by providing a waste receptacle for use in conjunction with a roll of bags. The waste receptacle is constructed and arranged to facilitate the removal of a full bag of waste and to provide ready access to a supply of new bags for lining the receptacle. Accordingly, the present invention provides a waste receptacle having a base constructed and arranged to support the receptacle in an upright position on a ground surface. The base has a bag storage space with a generally upwardly facing access opening. The bag storage space is constructed and arranged so that the roll of bags can be stored therein and accessed through the access opening. The waste receptacle further includes a first receptacle member and a second receptacle member providing first and second peripheral wall portions, respectively, and first and second interior bottom wall portions, respectively. The first and second receptacle members are movable relative to one another between 1) a normal, operative position and 2) a bag roll changing position. In the normal operative position, the first and second peripheral wall portions of the waste receptacle cooperate to provide the receptacle with a peripheral wall that extends generally upwardly from the base, and the first and second bottom interior wall portions cooperate to provide the receptacle with a bag supporting bottom wall that supports the bottom of a deployed bag within the receptacle. The first and second bottom interior wall portions together with the first and second peripheral wall portions define a waste receiving space. An upper edge portion of the first and second peripheral wall portions define a waste receiving opening that affords entry to the waste receiving space. In the bag roll changing position, the first and second receptacle members are moved apart from one another so as to increase the size of the waste receiving opening to facilitate access to the bag receiving space through the upwardly facing access opening so that a new roll of bags can be placed within the bag receiving space.
Other objects, features, and advantages of the present invention will become apparent from the following detailed description, the accompanying drawings, and the appended claims.
